Method of Use, and Composition of, First Responder Wet Wipes

ABSTRACT

A wet wipe useful for removing soot and other potentially dangerous carcinogens from skin surfaces is comprised of a primarily aqueous solution with additional ingredients effective in washing away, rather than embedding, soot and carcinogens in the skin.

This application is a divisional application which claims priority from U.S. Ser. No. 15/965,643, filed Apr. 27, 2018 which itself was a non-provisional application which claims priority from U.S. Ser. No. 62/490,624, filed Apr. 27, 2018, the disclosures of both of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention is in the field of wipes that can be used in emergency situations and, more particularly, for situations encountered by first responders, especially where soot is present.

BACKGROUND OF THE INVENTION

Fifteen years after 9/11 a number of reports and studies suggest a link between environmental exposures of 9/11 first responders and an increased rate of diseases and cancer for such persons. One concern is soot, which is an environmental exposure that fireman routinely encounter.

Firefighters know soot should be removed as part of a decontamination process after fighting a fire. Because it is not practical to remove clothing and take a shower or fully wash with a chemical wash at the site of a fire, firefighters have used wet wipes to help clean up from firefighting on site. A common wipe used is a simple baby wipe.

A number of companies sell wet wipes for use by firefighters which are advertised as good for use in decontamination by firefighters. Such wipes can contain products designed to moisturize skin and avoid irritation.

SUMMARY OF THE INVENTION

The present invention is generally directed to use of a wet wipe to remove a skin contaminant, such as soot, wherein the wet wipe is soaked with a predominantly aqueous solution in which additional ingredients are added to help remove soot and contaminants from the skin without embedding them within the skin. More particularly, the additional ingredients added to water (which has a wt. % of 90.00 to 98.00), by wt. %, include propanediol (0.10 to 5.00), a blend of extracts for skin-conditioning and soothing (0.001 to 1.00), a natural surfactant blend that softly rinses away dirt/impurities while also providing conditioning for the skin (0.10 to 5.000), a surfactant cleaning agent that also acts as an emulsifier (0.10 to 5.00), a chelating agent that sequesters metallic ions (0.001 to 1.00), a cleaning agent (0.001 to 1.00), a pH adjuster (0.001 to 1.00), an emollient, skin-conditioning, preservative booster (0.001 to 1.00), and preservatives (0.004 to 1.00).

Accordingly, it is primary object of this invention to provide an improved wet wipe useful by firefighters and other persons having skin surfaces contaminated by potentially harmful substances, an example of which is soot.

This and further objects and advantages of the present invention will be apparent to those skilled in the art in connection with the drawing and the detailed description of the invention set forth below.

DETAILED DESCRIPTION OF THE INVENTION

Although wet wipes are sold for use by fire fighters, and some fire fighters use baby wipes for the same purpose, such usage is not always helpful and, indeed, may actually be harmful in some instances. This is because baby wipes and possibly some other wipes as well can actually cause soot and/or carcinogens to embed in skin. Also, while skin care ingredients may be important for cosmetics, a primary objective of first responder wipes should be removal of harmful substances, not skin treatment; this is not to say that skin treatment has no place, just that it must not take primacy over removal of soot and/or carcinogens.

Wet wipes made in accordance with the present invention also have utility outside that of use by firefighters and are also useful by emergency medical technicians and non-professionals, such as consumers, that want a wet wipe effective for use in emergency situations or situations where it may be important to remove a contaminant from skin.

In accordance with the present invention, a preferred embodiment of a wet wipe solution has the following ingredients:

water, by wt. %, within a range of 90.00 to 98.00;

propanediol, by wt. %, within a range of 0.10 to 5.00;

a first blend of extracts, by wt. %, within a range of 0.001 to 1.00;

a natural surfactant blend, by wt. %, within a range of 0.10 to 5.00;

polysorbate 20, by wt. %, within a range of 0.10 to 5.00;

a blend of tetrasodium glutamate diacetate and sodium hydroxide, by wt. %, within a range of 0.001 to 1.00;

trisodium phosphate, by wt. %, within a range of 0.001 to 1.00;

citric acid, by wt. %, within a range of 0.001 to 1.00;

caprylyl glycol, by wt. %, within a range of 0.001 to 1.00;

benzalkonium chloride, by wt. %, within a range of 0.001 to 1.00;

phenoxyethanol, by wt. %, within a range of 0.001 to 1.00;
